Let’s look at how to play a D2 (D Second) chord on the piano. We’ll also learn the pattern for building any second chord.
What Are Second Chords?
Second chords are major chords with an added note. The added note is the second note of the matching major scale.
So to build a second chord, we’ll start by building a major chord. Major chords are built using the first, third and fifth notes of the matching major scale.
To convert the major chord into a second chord, we’ll add the second note of the matching major scale to the chord.

How to Play a D2 Chord
To play a D2 chord, we’ll start by building a D major chord using the first, third and fifth notes of the D major scale: D – F♯ – A.
Then we’ll add the second note of the same scale to the chord: E.
So to play a D2 chord on the piano, we’ll play:
D – E – F♯ – A
You may have also heard of “add9” chords. A Dadd9 chord is a D major chord with an added major ninth (the ninth note of the scale). Since major scales only have eight notes, a major ninth is actually the same note as the second note of the scale, just one octave up.
So the notes of a Dadd9 and D2 chord are the same, just in a different order:
Dadd9: D – F♯ – A – E
D2: D – E – F♯ – A
Other Chord Types
There are many other chord types you can learn. Here are some others:
Now you know how to play a D2 chord on the piano, and you can use that knowledge to build any second chord.
Using patterns to build chords is a lot of fun. Once you know the pattern for how to build a particular type of chord, you can use that pattern starting on any note!
